SAMUEL GRAHAM, OF LEBECK, MISSOURI.

VEHICLE-STANDARD.

SPECIFICATION forming part of Letters Patent No. 4 25,070, dated April8, 1890.

Application filed February 18,1890. Serial No. 340,863. (No model.)

To all whom it may concern.-

Be it known thatI, SAMUEL GRAHAM, a citizen of the United States ofAmerica, residing at Lebeck, in the county of Cedar and State ofMissouri, have invented certain new and useful Improvements in VehicleStandard Keys, of which the followingis a specification, reference beinghad therein to the accompanying drawings.

My invention relates to an adjustable key for securing avehicle-standardto the bolster, and particularly that class of standards shown anddescribed in my former patent, No. 416,910.

My object is to produce means whereby a vehiclestandard can beadjustably and at the same time securely fixed on the bolster end.

WVith this end in view my invention consists in certain peculiarities ofconstruction and combinations of parts more fully described hereinafter,and pointed out in the claims.

Referring to the accompanying drawings, Figure 1 represents a sideelevation of my complete arrangement of parts, Fig. 2, a bottom view,and Fig. 3 a detail view, of the key. The reference-letter B indicatesthe bolster end, and A the standard, preferably of the form shown in myprior patent before mentioned, having an encircling-band 0 arranged toloosely surroundthe said bolster. The bolster is provided with the usualbeveled lower surface a, and between this surface and the band 0 isinserted the key D. This key consists of a metallic plate, wedge-shapedin longitudinal section or elevation andv having a width equal to thatof the inside of the band C.

, The inner end of the key is bifurcated to form a pair of arms 0 and alongitudinal open slot 6 between them, and projecting spurs or lugs 01are formed on the inner ends of said arms. The arms 0 are also serratedor provided with teeth f 011 their under surfaces, as seen more clearlyin Fig. 3.

Through the bolster behind the standard extends a vertical bolt E, whichalso engages the slot 0, and is provided on its lower end with a nut gand washer h between the latter and the plain surface of the plate D.

The preferred construction of my device having been set forth, I willnow proceed to describe the mode of application of the same. The key isfirst placed in the band C to rest upon the lower wall of the same, withthe spurs d projecting from its inside edge. The standard is now placedon the bolster and set at the desired adjustment or distance from theouter extremity of said bolster. The key will next be driven home untilitis tightly wedged between the band C and the bolster, the arms 0passing on either side of the bolt E, which has been previously driventhrough the bolster. The nut g is then screwed up as tight as possibleon the bolt, and the teeth f in the upper surface of the arms 0, will beforced into the wood of the bolster, and the keythus rigidly clamped tothe latter. standard has been thus secured, it will be seen that it willmaintain a perpendicular position in relation to the bolster as thetaper of the surfaces of the wedge or key 0 corresponds to that of theunder side a of the bolster, and thus the lower face of the key and theupper surface of said bolster will be parallel and hold the standard atright angles to them.

It will be readily seen that the standard can be adjusted to anyposition 011 the bolster between the end of the latter and the bolt 9and locked at any point, and also that the lugs at will prevent theremovalof the keywithout the standard. It can be easily adjusted to suita narrow or wide tread vehicle, and also fitted to a key or other frame.It can be removed entirely, if desired, and can also be changed to suitthe swelling or shrinkage of the wagon-bed.

It is evident that my device might be varied in many slight ways whichmight suggest themselves to a mechanical mind, and hence I do not limitmyself to the exact construction herein shown.

Having thus described my invention, what I claim as new, and desire tosecure by Letters. Patent, isi 1. The combination of the bolster, thestandard, and a wedge inserted between them, substantially as and forthe purpose described.

2. A key arranged to be inserted between When the the standard andbolster, and consisting of a wedge-shaped plate provided with an adjustment-slot, substantially as described.

3. The combination of the bolster, the standard provided with a bandencircling the latter, a key inserted between said band and said bolsterand provided with a slot, and a bolt extending through said bolster andsaid slot, substantially as described.

t. A key inserted between the standard and ARTHUR W. ORR, (3120. N.JoNEs.
